Perhaps texi2pod.pl should move out of contrib to the gcc directory,
instead?

In any case, TEXI2POD should become "perl somewhere/texi2pod.pl" rather
than relying on #! (as per my patch
http://gcc.gnu.org/ml/gcc-patches/2000-12/msg00950.html ), so if it stays
in contrib then this would better be a configure patch.
